There are many different issues that can arise when setting up a system with the level of complexity that goes into configuring Windows to run on-top of GNU/LinuxLooking Glass. Below is a list of known issues with potential solutions:

=== NVIDIA Driver Error/Device Manager Error Code 43 When Launching Looking Glass the Desktop Doesn't Appear ===NVIDIA back in 2014, driver version 337.88 installed *''' Using an AMD GPU?

We ==== AppArmor ====AppArmor is a security application that can achieve this prevent Looking Glass from running. How to add security exceptions may vary on your distribution:===== Debian(Ubuntu) =====Start by making some tweaks opening the file <code>/etc/apparmor.d/abstractions/libvirt-qemu</code>. Now locate and edit the following lines to represent how they appear in the .XML fileexample:
